#### Explanation:
An important fact to note here is that:
${\sin}^{2} x + {\cos}^{2} x = 1$
Therefore:
${\sin}^{2} x = 1 - {\cos}^{2} x$
So if we put this into the equation given:
$\frac{1 - {\cos}^{2} x}{\cos} x = {\sin}^{2} \frac{x}{\cos} x$

Let $f$ be a real-valued function on the plane such that for every square $ABCD$ in the plane, $f(A)+f(B)+f(C)+f(D)=0.$ Does it follow that $f(P)=0$ for all points $P$ in the plane?

First, we expand everything we can:
$3 x - 2 \left(x - 5\right) < 3 \left(x - 1\right) - 2 x - 11$
$3 x - 2 x + 10 < 3 x - 3 - 2 x - 11$
